That’s what I mean, in fact. I understand, from your schedule, that you’ve already taken 3 courses over the summer, and did fine. But these specific classes you’re planning for this summer (General Physics, General Chem, Calculus 2) aren’t like normal college classes. They also require much more time because they’ll have 3-hour labs twice a week (each). In addition, they kick people’s butt in the best of times. Imagine all three classes you took before, rolled into one in terms of time commitment and complexity. Doubling that is the MAX anyone can handle. Taking both General Physics and General Chemistry over the summer is already quite a feat (one I don’t normally recommend, in fact - I’d recommend ONE of these+one art/social science class and even that is hard, but I understand you need to optimize your Pell Grant so 2 of these can be attempted especially since you’ve taken 5 or 6 classes a semester before.) It’ll be even harder than this since you’ll need to get A’s.
To get a BS, 4-year universities will require half the credits be earned at their institution.
You can’t really decide on a Physics major until you’ve taken General Physics.
Perhaps, look at colleges that offer a BSN and colleges that offer a Pre-PA path. UIC is pretty good and AFAIK students who completed all the required general education courses at an Illinois CC get their first 2 years automatically transferred, so that you’d have to complete major pre-reqs at the 4-year then the upper level classes OR you can complete your major pre-reqs/RN, then transfer to the 4-year.
